General information

Indicators and Dyes

Carl ROTH offers many indicators and dyes of high purity, which can be used in special applications.


Molisch’s test:

Molisch’s reagent is added to a diluted sample of monosaccharide and concentrated sulphuric acid is added down the sides of the test tube to form a layer beneath the solution. A purple ring forms at the interface between the layers. Since nucleic acids and glycoproteins also contain monosaccharides, they may react as well.
